https://issues.apache.org/jira/browse/HIVEMIND-24> Project: HiveMind
> Issue Type: New Feature
> Components: library
> Affects Versions: 1.0
> Environment: All
> Reporter: Kurt R. Hoehn
> Priority: Minor
>
> I was wondering if I could contribute a DataSource builder factory to the Hivemind Library. Here is the hivemodule.sdl that shows its configuration.
> I believe that this would be a nice to have when implementing data drivin services.
